A commercial vehicle (10), comprising an electric drive unit (100) and a cooling system (200). The cooling system comprises a main circuit line (210) with a pump (212) for pressurizing the main circuit line at a working pressure. An auxiliary circuit line (220) extends from the main circuit line downstream of the pump towards a first auxiliary heat exchanger (221), and comprises a pressure valve (213) that is passively operable between a first state and a second state by the pump adapting the working pressure in the main circuit line. In response to a temperature of the electric drive unit exceeding a temperature threshold, the pump increases the working pressure for thereby operating the pressure valve to switch from the first state to the second state.
